REGfULA'rIN'erV RADIATOR PLUG.

Application mea Ap`ri1 1s, 1925. `semi No. 24,o5s.

To all whom t may concem: f

Be it known that I, JAY H. KELLER, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Regulating Radiator Plug, of which the following is a specification. n

My invention relates to regulatingl radiator plugs in which the longitudinalpassage way of a body portion is closed by an obliquely entering regulating screw.

The objects of my invention are to furnish a device which can be manufactured at very little exp-ense; by means of which the regulation of the flow in a radiator can be eected with great nioety and without the necessity of detaching the outlet pipe from the radiator; and which distributes vthe flow over a large area and thereby minimizes pitting and wire drawing.

Other objects and advantages are to be found in the construction and arrangement` of parts as will be described in the specication, and particularly pointed out in the appended claims. i

I attain these objects with the mechanism illustrated in the accompanying drawing, in which: f

Fig. 1 is a conventional illustration of a radiator with the regulating radiator plug in place. f f

Fig. 2 is a vertical longitudinal section through the regulating radiator plug.

Fig. 3 is an end view of Fig. 2.

Similar numerals refer to similar parts throughout the several views. y In order to appreciate the import of my invention it may be stated that in hot water heating, especially where forced circulation is employed, the water in the radiators nearest to the boiler will circulate with greater rapidity, Yand therefore leave to theseradiators more than their allotted share of the total heat units, while the radiators located at a farther distance remain comparatively cold. L

I-Iitherto this defect was remedied by unscrewing the outlet pipe of each radiator and then partly closing said outlet with a disk having a small perforation in the center, the size of the perforation however had to be ascertainedby trial. In other words, a very small perforation was employed first, and if that proved incorrect, the outlet pipe had to be vunscrewed again and the perforation enlarged, perhaps va number -of times, until the-water circulated evenly throughout the entire system. Moreover, pitting and wire drawing were apt to enlarge some of the perforations in course of time and the tedious process of equalization had to be repeated anew. vIn my invention dierent means and methods are employed, to witz-- In the radiator 1, having the customary inlet pipe 2, and outlet pipe 3, the regulating radiator plug is inserted between the radiator 1 and the. outlet pipe V3. This regu lating radiator plug consists of a hollow cylindrical body portion 4 whose one end is provided with the external or male thread 5 which is to be screwed into theradiator, that same end of the body portion 4 is closed by a vertical wall 6 with a passage way 7 in longitudinal direction near the bottom of the body portion 4. This passage way should be large enough to comply with the maximum requirements of the system. The terminal of the passageway 7 within the chamber 8 is at a portion of the inner side of the wall 6 arranged at an angle tothe remaining portion o-f the wall, and is countersunk at the proper angle to furnish a tight seat for a screw Aplug 9 which enters the body portion lat an angle of approximately forty-five degrees and passes through a thickened wall parallel to the valve seat. The Outer terminal 10 of the screw plug 9 1s square for the use of a wrench or Spanner. A counter nut 11 is filled with packing 12 insures a steam tight joint. The thread 13 of the screw plug 9 should be of relatively small pitch in order to permit of suiiicient refinement vin adjustment. That part ofthe body portion'4c which is entered by the screw plug 9 should be shaped properly to furnish a seat for the counter-nut 11. The end of thebody portionl opposite the wall 6 is pro- Having thus described my invention, it..

will be seen that my objects have been accomplished and, though I have shown the l preferred form of construction, I reserve to myself the right to make minor changes .providing I do not violate the spirit and y principle of my invention.

I claim:

l. A radiator plug comprising a, body adapted to enter a radiator and having an inner vvertical Wall, a Valve seat integral with said Wall and at an angle thereto, a Second Wall parallel to the seat and carrying a. Valve Stern and head 'cooperating With the seat. Y

adapted to enter a radiator and having` an inner Vertical Wall, a Valve seat at the bottorn end'of said Wall, Said seat being integralk with the Wall `and at an angle thereto, and

a second Wall parallel to the seat, said 'sec- 2. A radiator plug comprising a loody' ond Wall being thickened and carrying a With said Wall and at an angle thereto, Va` second thickened Wall parallel vto the seat and carrying a Valve stein and head cooperating` With the seat.
